- 摘要:
- 为探讨印度夏季风异常变化对高原夏季降水以及相应的异常环流系统的影响,利用 1973-2014年NCEP(2.5°×2.5°)逐月再分析资料、中国逐月降水格点资料及印度逐月 降水资料,采用相关、合成分析等方法,结果发现:(1)印度夏季风影响下的高原东部、西部地 区夏季降水呈现相反的变化特征,即印度夏季风强年(弱年)高原西部降水偏多(偏少),高原东 部降水偏少(偏多)。(2)印度夏季风强年(弱年),对流层上层南亚高压偏强且偏西、偏北(偏 弱且偏东、偏南); 对流层中低层印度半岛是异常气旋(反气旋)环流系统,青藏高原西部是异 常气流辐合(辐散)流场,东部则是异常辐散流场(辐合中心或辐合带)。(3)综合印度夏季风强 弱年对流层中异常环流系统变化的影响,印度夏季风强年(弱年),青藏高原西部异常上升运动 增强(减弱),水汽通量异常辐合(辐散),导致降水异常偏多(偏少); 青藏高原东部则是相反的 异常变化特征。
- Abstract:
- Based on the NCEP(2.5°×2.5°)reanalysis data from 1973 to 2014, the China and Indian monthly precipitation data. To discussed the abnormal changes of India summer monsoon impact on Summer Precipitation over the plateau and the corresponding abnormal circulation system, through correlation analysis and synthesis analysis. The results show that:(1)The summer precipitation in the eastern and western Tibetan Plateau has an opposite trend under the influence of the Indian summer monsoon, in Indian summer monsoon strong year(weak year), the more(less)precipitation in the western part of the Tibetan Plateau, but the less(more)precipitation in the eastern part of the Tibetan Plateau.(2)In Indian summer monsoon strong year(weak year), the South Asia High in the upper troposphere is strong and westward, northward(weak and eastward, southward); In the middle and lower troposphere, India peninsula is an anomalous cyclonic (anticyclone)circulation system. The western part of the Tibetan Plateau is an anomalous convergence(divergence)flow field, while the eastern part is an anomalous divergence flow field(convergence center or convergence zone).(3) comprehensive the influence of the variation of the anomalous circulation system in the troposphere during the India summer monsoon. India summer monsoon stronger(weaker), Western Tibetan Plateau abnormal rising motion increased (reduced), water vapor flux convergence(divergence), which will lead to more (less)precipitation anomaly. While the eastern Tibetan Plateau was the opposite anomaly characteristics.
